Hey Steven,
In scouring around for info that might help you, I went to the SaabNet FAQ's and found this interesting tidbit in regards to the Idle Air Control Valve.
Idle Air Control Valve - The AIC for the LH 2.4, 2.4.1, and 2.4.2 differs from the LH 2.2 in that the reversible motor is replaced by a solenoid. The coil receives pulse signals from the ECU. When activated, the coil overcomes a mechanical spring that keeps the valve closed. This allows a specific volume of air to flow past the throttle butterfly in the intake manifold. In the event of a fault, the opening pulses terminate and the spring pulls the valve to the end position. The air flow through the valve in this position (Limp Home) is greater than during normal operating conditions. This gives an idle speed of 1,200 to 1,500 rpm.
Does that idle speed sound familiar?
I have included the link to the page I referenced.
